Long-range entanglement from measuring symmetry-protected topological phases
Nathanan Tantivasadakarn, Ryan Thorngren, Ashvin Vishwanath +1
A fundamental distinction between many-body quantum states are those with short- and long-range entanglement (SRE and LRE). The latter cannot be created by finite-depth circuits, u…
Building models of topological quantum criticality from pivot Hamiltonians
Nathanan Tantivasadakarn, Ryan Thorngren, Ashvin Vishwanath +1
Progress in understanding symmetry-protected topological (SPT) phases has been greatly aided by our ability to construct lattice models realizing these states. In contrast, a syste…
Pivot Hamiltonians as generators of symmetry and entanglement
Nathanan Tantivasadakarn, Ryan Thorngren, Ashvin Vishwanath +1
It is well-known that symmetry-protected topological (SPT) phases can be obtained from the trivial phase by an entangler, a finite-depth unitary operator . Here, we consider obt…
Fusion Category Symmetry II: Categoriosities at c = 1 and Beyond
Ryan Thorngren, Yifan Wang
We study generalized symmetries of quantum field theories in 1+1D generated by topological defect lines with no inverse. This paper follows our companion paper on gapped phases and…
